Hi in this article i explain about how to get the current value of the first element in the set of matched elements in jquery
$('select.foo option:selected').val(); // get the value from a dropdown select
$('select.foo option:selected').val(); // get the value from a dropdown select
$('select.foo').val(); // get the value from a dropdown select even easier
$('input:checkbox:checked').val(); // get the value from a checked checkbox
$('input:radio[name=bar]:checked').val(); // get the value from a set of radio buttons
